Ultra-small Package Load Switch ICs for Mobile Devices: TCK101G, TCK102G

The TCK101G and TCK102G are low voltage operation, low ON-resistance, and low consumption current load switch ICs with additional functions.
Employing a newly developed micro CMOS process, these products feature low voltage operation at 1.1V and a low ON-resistance characteristics of 55mΩ (typ.) (VIN = 3.3V, IOUT = 500mA) in a 0.4mm pitch ultrasmall WCSP6B (0.8mm × 1.2mm, t: 0.64mm (max.)) package.
An inrush current limiter and overtemperature protection circuit come as standard additional functionality, and an output auto-discharge function is offered depending on the product type. With a footprint of only 0.96mm2, these load switch ICs are suitable for applications requiring high-density packaging, such as mobile devices.
